Parameters
group-number: Specifies a port block group by its ID. The value range for this argument is 0 to 65535.
Usage guidelines
You can apply multiple port block groups to one interface.
After you apply a port block group to an interface, the system automatically computes the NAT444
mappings and creates entries for them. When a private IP address accesses the public network, the
private IP address is translated to the mapped public IP address, and the ports are translated to ports in
the selected port block.

[Sysname] interface gigabitethernet 2/0/1
